Definitions

  • the present invention relates to a growth promoting agent for the root of a plant whose roots, stems and leaves can be distinguished each from the other two. More specifically, this invention relates to a plant-root growth promoting agent comprising inosine as the effective ingredient and also to a method for promoting the root growth of such a plant, which method comprises applying inosine as the effective ingredient thereto, as well as to the plant bodies, including leaves of leaf vegetables and fruit of fruit vegetables, of plants to which such a plant-root growth promoting agent has been applied during their life time.
  • nucleic acid-related substance is applied to plants.
  • Several examples where a nucleic acid-related substance is applied to plants are conventionally known.
  • a plant growth regulator which comprises, as effective ingredients, ⁇ -indoleacetic acid or the like and at least one substance selected from the group consisting of a purine base, pyrimidine base, nucleoside and nucleotide, each available by the decomposition of nucleic acid.
  • nucleic acid bases, nucleosides and nucleotides which are obtained by the decomposition of nucleic acid and differ in the decomposition degree are treated as substances having the same effects(i.e., equivalents).
  • the plant growth regulator is a composition which requires, as the essential condition, the combined use of a nucleic-acid decomposition product and ⁇ -indoleacetic acid or the like.
  • the plant growth regulator is applied by (1) immersing seeds, radicles or seed tubers in a solution of the regulator; (2) spraying the solution to young fruit bodies of mushroom, young fruits, floral organs or phylloplanes; or (3) employing the above two treatments in combination at appropriate times selected as needed (for example, subjecting seeds to the immersing treatment, and then the phylloplanes of the plants grown from the seeds to the spraying treatment), which treatments are utterly different from the application method according to the present invention in which the growth promoting agent is applied in such a way that it promotes directly the growth of plant roots.
  • Japanese Patent Publication kokoku No. 16310/1974 is disclosed a growth regulator for fruit vegetables which comprises, as effective ingredients, a plant hormone such as chlorophenoxyacetic acid and at least one substance selected from the group consisting of non-decomposed nucleic acid pyrimidine bases, purine bases, nucleosides and nucleotides, the last four being obtainable by the decomposition of nucleic acid.
  • a plant hormone such as chlorophenoxyacetic acid
  • nucleic-acid related substances are used in order to reduce the generation of various physiological disorders of crops caused by the application of the above-described plant hormone and to increase the expected effects to be brought by the application of the plant hormone, the combined use of a plant hormone and a nucleic-acid related substance is the essential condition.
  • a solution of the above growth regulator for fruit vegetables is desired to be distributed onto the plant body; this distribution treatment is effected at the flowering season to such an extent of wetting the flower clusters or flower organs with the solution by spraying the solution with the use of a sprayer over the flower clusters, the flower organs or the whole crop or by coating or immersing the flower clusters or flower organs with or in the solution.
  • These treatments are utterly different from the application method of the plant-root growth promoting agent of the present invention.
  • Japanese Patent Publication kokoku No. 17670/1979 is disclosed a method for improving the leaf life of a foliage plant, which comprises bringing the leaves, the leaf stems or petioles, or the cut ends thereof, of a matured foliage plant into contact with one or more than one of nucleotides and nucleosides (inosine being given as an example).
  • Japanese Patent Application Laid-Open kokai No. 56759/1973 is disclosed a method for promoting the germination of pollen of a fruit tree, which comprises spraying the flower buds of the fruit tree at its bud time with a single solution or a mixed solution of at least two of nucleotides, nucleosides (inosine being given as an example) and nucleic acid bases.
  • Japanese Patent Laid-Open kokai No. 68848/1985 is disclosed a method for prolonging the life of cut flowers, which comprising applying a mixed solution of inosine and calcium chloride (as a liquid used for natural flowers displayed at a flower shop or a liquid poured in a flower bowl or vase) onto natural flowers.
  • DE-A-3910061 discloses a phytosanitary agent which contains two amino acids and/or natural carboxylic acids, purines and/or pyrimidines and vitamins.
  • the agent is used for preventing and controlling plant diseases of biotic origin.
  • nucleic-acid related substances for plants is conventionally known, but in the said use, the combined use of these substances with other substance is the essential condition. Even if various nucleic-acid related substances are used singly, they are put in the same category without being distinguished from each other. In addition, the application method of effective ingredients is utterly different from that of the present invention.
  • the growth of roots is an important basis for plants to grow further. Based on the sound growth of roots, the plant extends its leaves, puts forth flower buds, is pollinated, bears fruit, and enlarges the fruit. From such a viewpoint, there has accordingly been a demand for the development of a new substance or composition, or a new method of promoting the growth of plant roots.
  • An object of the present invention is therefore to provide a novel growth promoting agent composition for plant roots and a novel method for promoting the growth of plant roots.
  • the present invention therefore relates to a method for promoting the growth of plant roots, which comprises applying a plant-root growth promoting agent comprising inosine to the soil or, in the case of hydroponics, to the hydroponic water.
  • the present invention provides a method for promoting root growth of a plant, which comprises applying inosine to soil in an amount of 0.05-0.5 ppm based on the soil, or to hydroponic water in a concentration of 0.1-2 ppm based on the hydroponic water, the plant being in said soil, or in said hydroponic water, and being selected from the group consisting of leaf vegetables, fruit vegetables, root vegetables, flowers, fruit trees and grains.
  • plant-root growth promoting is meant in this specification that plant roots are increased in number, length (long or short) and/or thickness (slender or diverent), compared with cases where the plant-root growth promoting agent of the present invention is not used, the other conditions being the same.
  • the terms also include the stimulation or promotion of plant root germination.
  • Plants to which the plant-root growth promoting agent of the present invention is to be applied can be those plants at large which have clearly differentiated roots, stems and leaves, and specific examples thereof include leaf vegetables, fruit vegetables, root vegetables, flowers, fruit trees and grains.
  • Inosine does not necessarily need to be a purified product.
  • an inosine product can be an inosine fermentation broth per se .
  • it can take the form such as a concentrate or concentrated and dried product of an inosine fermentation broth, a crude product of inosine separated from an inosine fermentation broth, an inosine-containing intermediate treatment fraction upon the preparation of a nucleic-acid related substance (nucleotide, nucleoside, nucleic acid base, etc.) by the decomposition of nucleic acid, an inosine-containing fraction of a processed inosine fermentation broth or the like.
  • a nucleic-acid related substance nucleotide, nucleoside, nucleic acid base, etc.
  • inosine inosine in the form free from impurities which may cause pollution or putrefaction.
  • the plant-root growth promoting agent containing inosine as the effective ingredient can be formed into a liquid preparation in which the agent has been dissolved or dispersed in a suitable solvent such as water so as to carry out its application through soil or hydroponic water conveniently or can be formed into a powder or granular preparation by using a proper extender or binder.
  • inosine into its alkaline aqueous solution which has been added with an inorganic alkali such as alkali metal hydroxide, e.g., NaOH or KOH, alkaline earth metal hydroxide, e.g., Mg(OH) 2 , or a basic amino acid such as lysine or arginine.
  • alkali metal hydroxide e.g., NaOH or KOH
  • alkaline earth metal hydroxide e.g., Mg(OH) 2
  • a basic amino acid such as lysine or arginine.
  • Examples of the application method of such a plant-root growth promoting agent include applying the agent to the soil in advance, then followed by sowing it with plant seeds, and adding the agent to hydroponic water to dissolve the former in the latter in the case of hydroponic cultivation.
  • the agent can be useful for the purpose of recovering a fruit vegetable such as strawberry or melon from the exhaustion attributed to fruit bearing, or preventing the fruit bearing exhaustion.
  • other examples of the application method include applying the agent at a proper time during cultivation, for example, by adding to the soil at the roots of the fruit vegetable or by adding it to the hydroponic water when the symptoms of bearing exhaustion are observed or when bearing exhaustion is expected even if there are no actual symptoms thereof observed.
  • the plant-root growth promoting agent according to the present invention is used in an amount which permits rooting (i.e., root germination) or root growth superior to those of a plant cultivated under the same conditions except that the plant-root growth promoting agent of the present invention has not been applied.
  • This amount can be determined by some preliminary comparison test which is feasible by those skilled in the art.
  • the concentration of the inosine moiety can be as low as 5 to 50 g per 100 tons of soil (0.05 to 0.5 ppm).
  • the concentration of inosine can be set at 0.1 to 2 ppm per hydroponic water, different from the case of the application to soil.
  • the agent of the present invention therefore exhibits plant rooting action or plant-root growth promoting action at such low concentrations.
  • Gibberellin which is one of representative plant hormones causes disorders in the plant when the concentration is set wrongly, that is, set at too high a concentration, at the using time, while it has no effects when the concentration is insufficient. This is commonly said about plant hormones.
  • Chlorophenoxyacetic acid-based and ⁇ -naphthoxyacetic acid-based compounds are known as so-called plant hormones and application of them to, for example, fruit vegetables, is effective for the growth promotion or fruit time acceleration of the fruit;
  • plant hormones Chlorophenoxyacetic acid-based and ⁇ -naphthoxyacetic acid-based compounds
  • application of them to, for example, fruit vegetables is effective for the growth promotion or fruit time acceleration of the fruit
  • plant hormones Chlorophenoxyacetic acid-based and ⁇ -naphthoxyacetic acid-based compounds
  • application of them to, for example, fruit vegetables, is effective for the growth promotion or fruit time acceleration of the fruit
  • Such physiological disorders include abnormal bending of the stems or leaves, shrinkage of the leaves, generation of callus on the stems, leaves or peduncles, deformity of fruit, and frequent generation of hollow fruit.
  • the object of the invention concerned is to provide a fruit-vegetable growth regulator useful in agricultural management, based on the findings that the generation of the above-described physiological disorders can be reduced and at the same time expected effects can be heightened by the mixed use of chlorophenoxyacetic acid-based and/or ⁇ -naphthoxyacetic acid-based compound(s) and nucleic acid or decomposition product(s) thereof.
  • inosine is not a plant hormone, can be used at various application concentrations, does not cause any particular disorders of the plant even used in an excess amount, is made use of by soil microorganisms soon after application and does not cause any obstacles but becomes useful for the soil improvement.
  • Small-sized lily bulbs are cheap but put forth only one or two flowers per bulb when grown, while large-sized ones are expensive but put forth as many as four or five flowers per bulb.
  • some lily flower cultivators purchase small-sized lily bulbs from lily bulb cultivators, and rear them into large-sized bulbs by cutting off flower buds from lily trees grown from such small-sized bulbs. In the following year, the lily flower cultivators plant such large-sized bulbs, and ship the lily flowers put forth by the large-sized bulbs.
  • the roots of Brassica Rapa var. pervidis showed a marked growth by the administration of inosine in an amount of at least 0.05 ppm, preferably 0.5 ppm, relative to the soil.
  • FIG. 1 is a photograph of the water-washed roots of Brassica Rapa var. pervidis harvested as described above. Although this photograph does not clearly show the difference in the growth of the above-ground parts of Brassica Rapa var. pervidis between the inosine-added plots and the control plot, the growth in the test plots was superior to that of the control plot in the subterranean parts, more specifically, superior in the length and the number of the roots and moreover, in the quality of the above-ground parts (leaf part) as leaf vegetable. Thus, it has been found that the addition of inosine was effective even in an amount of only 5 to 20 g per 100 t of soil.
  • the inosine-applied plot was also higher in the sweetness degree (i.e., sugar contents or Brix degree) of the fruit. Described specifically, three delicious-looking, fine-shaped melons were selected from the melons harvested from each of the inosine-applied plot and the inosine-free plot, and their sweetness degree was evaluated by 10 people. As a result, all the members evaluated that the melons from the inosine-applied plot had stronger sweetness and were delicious compared with those from the control plot.

  • Results are shown in Table 6 below. Concerning each plot, the above-ground parts (height and weight) and subterranean parts (root weight) of 8 cucumber seedlings were measured and the average values were calculated, which are shown in Table 6 below. Incidentally, the roots were weighed after dried.
  • FIGS. 4A, 4B and 4C photographs showing the seedlings in the pots, the seedlings taken out together with the soil from the pots, and the seedlings after washed with water to show the condition of the roots, are shown in FIGS. 4A, 4B and 4C, respectively. Also from these photographs, the application effects of inosine can be understood.
  • Peas were subjected to the cultivation test in the same manner as in Example 8. Supposing that the weight of the combined vine and foliar weight and that of the roots of the control peas (application-free plot) were 100 each, the vine and foliar weights were 107 and 120 and the root weights were 120 and 120 when inosine was applied in amounts of 30 g/10 ares and 50 g/10 ares, respectively. Thus, application effects of inosine were recognized.
  • the present invention has made it possible to carry out plant-root growth promotion easily and, in turn, to carry out rearing or thickening of leaves, floral buds, fruit bearing, or fruit easily.
  • FIG 1 A first figure.
  • the Brassica Rapa plants in the array shown correspond to test plots as follows: Control plot (1) 10g plot (1) 30g plot (1) Control plot (2) 10g plot (2) 30g plot (2) 5g plot (1) 20g plot (1) 50g plot (1) 5g plot (2) 20g plot (2) 50g plot (2)
